Study Notes
Visual Angle
- Reflected light from objects forms an upside-down image on the retina.
- The size of the image is specified as a visual angle.
Touch and Feedback
- Touch provides vital feedback about actions performed, such as feeling keys move or the orientation of a mouse.
Human-Computer Interaction (HCI)
- HCI focuses on the human, the user, as the central figure in interactive systems.
- Understanding cognitive psychology is crucial, including aspects like perception, information processing, problem-solving, and object manipulation.
Cognitive Psychology in HCI
- Cognitive psychology helps us understand how humans perceive the world, process information, and solve problems.
Human Information Processing System
- The human information processing system is composed of multiple subsystems, each with its own processor and memory.
- The complexity of these subsystems varies based on the complexity of tasks they perform.
Principles of Operation
- The model of human information processing includes principles of operation that dictate system behavior under specific conditions.
